REVISION SUMMARY
  The EGL platform might go away at any time through reconfiguration or because
  of a graphic error. KWin then resets the graphics. The dmabuf implementation
  must respect that and recover from a graphics reset by recreating all EGL
  images for existing buffer.
  
  This assumes that we won't change our graphics API mid-session and that
  supported plane and modifier configuration stays constant.
  
  In practise we remember all current dmabufs in a single map and only remove
  them if the client did destroy the resource.
  
  BUG: 411980
  CCBUG: 413403
  FIXED-IN: 5.17.2

TEST PLAN
  Applied screenedge configuration without crash.
